✦ Synopsis

thin-layer plates, removal of the spots and extraction of the silica gel with methanol containing 5 % of concentrated ammonia solution are recommended. After excitation with the 365 mu Hg line, the intensity of fluorescence of the extract is determined at 520 mp for DANS-amides and at 530 m p for phenol-and pyrocatechol-amine derivatives. Reproducibility is 3-5 for concentrations of 2x 10-10 mole/cm3.
